High-cohesion divertor alloy - DFT (Ta-Re-W-Ti-V)

BR-L2-A32revisedverification card freeze 2026-08-27

What was computed

LOCAL DFT (L3_DIV) converged: Ta-containing divertor alloy (Cr1Ta5Ti3V3W4) formation +0.015 eV/atom near-neutral (matches fleet +0.016, resolved A9); Ta-free variant A37a even slightly stable (-0.002)

Reproduce this

# Reproduce BR-L2-A32 against the frozen record
pip install kronos-toolkit   # github.com/KronosFE/kronos-toolkit
python -c "from kronos_toolkit.verify import run_regression; run_regression()"
# BR-L2-A32 is anchored in the 2026-08-27 freeze spine (verdict: revised).
